Gionatan De Pas is a member of the Italian designer trio De Pas/D'Urbino/Lomazzi, who met while studying at Milan Polytechnic and opened a joint practice in Milan in 1966. Gionatan De Pas, Donato D'Urbino, and Paolo Lomazzi collaborated very closely on all projects. The De Pas/D'Urbino/Lomazzi trio became famous over night in 1967 for "Blow", an inflatable armchair of PVC film they designed for Zanotta. The first inflatable armchair to be mass produced, "Blow" became an icon of Pop culture. In 1970 Gionatan De Pas, D'Urbino, and Lomazzi had another hit: "Joe", a leather armchair in the form of an outsize baseball glove, named, of course, after the legendary American baseball player Joe DiMaggio. Both pieces of seat furniture represented a clean break with traditional notions of seating and living. In 1973 De Pas/D'Urbino/Lomazzi designed "Sciangai" – a bunch of upright wooden roods 1.5 meters long that looked giant chopsticks but was a clothes stand. All three designers shared this tongue-in-cheek sense of humor and it informs almost all their designs. The trio developed designer objects for Artemide, Alessi, Cassina, Driade, Poltronova, Stilnovo,Valenti, and Zerodisegno. Gionatan De Pas died in 1991 but D'Urbino and Lomazzi continued to run the Milan practice.
